Lag on line and intermittent service
 

Greetings all,

I am receiving intermittent service problems on my 10mb NTL cable line. Download speeds fluctuate widely and I am experiencing lag and timing out connections.

I have tried resetting the modem, another network card, and connecting the modem to my pc instead of through my router, and have checked there is nothing wrong with the network settings on my pc (and my pc is obviously not downloading/uploading)

Here is a screenshot from a recent ping

as you can see my connection is all over the place!
Anything i should know/check/look up before I contact customer services?

Thanks in advance
Ben
